I am not sure how to address this problem. I would like the user to be able to mark points along a road that will mark a route (lines will connect the waypoints to show the route). I know how to do this. After they have defined a route, I want to be able to run a script that will return lat and long positions every X feet along the route. This is the point that I am having a hard time with. I have played around with drawing a radius around each point and trying to find where that intersects the route, and haven't had any luck. Does anyone have any suggestions on how I might do this? The purpose is to be able to have points every 50 feet that I can compare to GPS data to tell if a vehicle is on the route that has been defined.
